自签名证书的 HttpClient 4.1.x 错误（javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated）答案

【问题标题】：HttpClient 4.1.x error for self signed certificate (javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated )自签名证书的 HttpClient 4.1.x 错误（javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated）

【问题描述】：

我正在尝试使用带有 clientAuth=true 的自签名证书配置 Tomcat6，然后使用 HttpClient 4.1.x 在客户端调用 Tomcat 服务器。

我按照http://virgo47.wordpress.com/2010/08/23/tomcat-web-application-with-ssl-client-certificates/ 中提供的说明进行操作，当我从浏览器或 openssl 客户端进行测试时，它工作正常（我运行了命令“openssl s_client -cert client.crt -key client.key -CAfile ca.crt -connect localhost:8443")。

我面临的问题是 HttpClient。我编写了以下代码来创建 HttpClient

    private DefaultHttpClient creatHttpClient(KeyStore keyStore, 
        char[] keyStorePassword, KeyStore trustStore, char[] trustStorePassword) {
    try {

        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
                TrustManagerFactory.getDefaultAlgorithm());
        trustManagerFactory.init(trustStore); // This contains CA certs
        TrustManager[] tm = trustManagerFactory.getTrustManagers();

        KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(
                KeyManagerFactory.getDefaultAlgorithm());
        keyManagerFactory.init(keyStore, keyStorePassword); // This contain client private key
        KeyManager[] km = keyManagerFactory.getKeyManagers();

        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(km, tm, new SecureRandom());

        SSLSocketFactory sslSocketFactory = new SSLSocketFactory(sslContext, 
                SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 10000);
        HttpConnectionParams.setSoTimeout(params, 30000);

        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(new Scheme("https", 
                443, sslSocketFactory));

        ClientConnectionManager clientConnectionManager = 
                new ThreadSafeClientConnManager(schemeRegistry);

        final DefaultHttpClient httpClient = new DefaultHttpClient(
                clientConnectionManager, params);
        return httpClient;
    } catch(Exception e) {
        throw e;
    }
}

为此，我收到了

    javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

我启用了调试

    static
    { System.setProperty("javax.net.debug", "ssl,handshake,trustmanager"); }

我收到以下调试日志

    main, handling exception: java.lang.RuntimeException: Unexpected error:                      java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
    main, SEND TLSv1 ALERT:  fatal, description = internal_error 
    main, WRITE: TLSv1 Alert, length = 2
    main, called closeSocket()
    main, IOException in getSession():  javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
    main, called close()
    main, called closeInternal(true)
    main, called close()
    main, called closeInternal(true)

在这种情况下可能出现什么问题？我不想忽略 ssl 证书错误，而是想正确进行身份验证。

【解决方案1】：

我解决了自己的问题。问题是我正在使用

加载密钥库和信任库

InputStream ksin = this.getClass().getResourceAsStream("client.jks");
InputStream tsin = this.getClass().getResourceAsStream("cacerts.jks");

& 在 Junit 测试中使用了这些行，它无法找到 .jks 文件。

我通过以下方式解决了这个问题

if(0 == keyStore.size()) { throw new RuntimeException("Keystore is empty"); }
if(0 == trustStore.size()) { throw new RuntimeException("Truststore is empty"); }

在密钥库和信任库初始化之后。

所以，我将这些行改为

InputStream ksin = Thread.currentThread().getContextClassLoader().getResourceAsStream("client.jks");
InputStream tsin = Thread.currentThread().getContextClassLoader().getResourceAsStream("cacerts.jks");

& 一切正常。
